Summary
This study presents a serial sectioning method for creating 3D models of virus-infected cells using transmission electron microscopy. This technique offers a cost-effective and non-destructive way to visualize cellular structures and viral assembly complexes.
Area of Science:
- Cell biology
- Virology
- Microscopy
Background:
- Understanding virus-infected cells requires detailed structural analysis.
- Previous methods for 3D reconstruction have limitations in terms of cost and sample volume.
Purpose of the Study:
- To present a serial sectioning method for generating 3D models of virus-infected cells.
- To highlight the advantages of this method for studying viral assembly and cellular compartments.
Main Methods:
- Sample fixation using high pressure freezing and freeze substitution.
- Serial sectioning of resin-embedded samples.
- Transmission electron microscopic imaging for 3D reconstruction.
Main Results:
- Successful generation of a three-dimensional model of an HCMV infected cell.
- Detailed insight into a virally induced compartment.
- Demonstrated the ability to reconstruct relatively large volumes, such as whole cells.
Conclusions:
- Serial sectioning is a cost-effective and non-destructive method for 3D cell imaging.
- The method allows for detailed structural analysis of virus-infected cells and viral complexes.
- Sections can be re-analyzed or processed for further investigations, enhancing scientific discovery.

01:03Fixation and Sectioning
Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Three-dimensional imaging techniques are essential in cell biology, allowing researchers to visualize intricate cellular structures with high resolution. Two prominent methods, Differential Interference Contrast Microscopy (DIC) and Confocal Scanning Laser Microscopy (CSLM), provide distinct advantages for imaging live and thick specimens, respectively.Differential Interference Contrast MicroscopyDIC microscopy enhances contrast in transparent, unstained samples by converting phase...
